. .I, DAVID J. 'Fnmmm'of Wheeling, in the county of Ohio, State of .WestVirginia, have invented a, new and improved Nail and Tack-Plate Feeder,of which the following is aA specification.

ulirat'ie aml'Obi'e'cts of the Invention.

'llhe machine is constructed with .reciprocating sliding table, carryinga. number of "nail-plate feeders,-

which are advanced alternately to lthe vpoint .at which the nail-blanksare eut nii'.

Some of the main features consist of- First, adevi'cefor changing thefeed eaclrtiinethe.

sliding. table reaches the end of itsstrok.

Second, a device for shitting the racks, whereby'they are adaptedforgiving the semi-rotation to the, feeders on vone or the other side ofthe point at which the eut-ter acts.

Third, a guard-plate keeps the plates in thefeeders,

and the latter in the desired position.

Description of the .Aceo'hqiaiiy'ing Drawing.

Figure 1 is a top .view et'4 the machine.

.Figure 2 is a side elevation. v Figure 3 is a transverse verticalsection on `the line FigureA is a detached view, showing the mode of'shifting thefeed-tappet to reveise the 'motion ofthe. sliding table.

General Descri'pti'0n.

A is a bed, raised-upon legs B,'and supporting the sliding table0,'jwhieh is reciprocated in the direction of its length by means of `acog-wheel, D, beneath which engages a rack, E, beneath thetable.

The wheel D is k'eyed upon 'a shaft-11, which is turned by a lever, G,`pawl H, and toothed wheel I.

The motion of the parts of the machineis derived-v fiom the lever Glwliichis reciprocated hy the 'prime motor.

After the slidingtable'hasbeen carried tothe end of its range in onedirection, a stud, c, on. the side of the'table, touches an arm, J,which extends upward from and is sleeved `npon the shaft F.

'lhe arm J tips the double pawl H, and causest to act against the otherside of the teeth on the ratchetwheel, and thus to rotate the shaft in adirection the reverse of the former.

On the table G-are one or inore feeders', 1i, which holdthc nail-plates,and present themat the gap l,

in the guard-plate, in which the cutter works; -iii the illustration itis arranged for four feeders.

The feeder K consists of a 'barrel and a pair of grocved guide-bars, kk, the said Agrooves forming a lchannel, along which the nail-platesslip.

.These gudesmay be made adjustable toward'and from each other, so as` tovallow for different -widths of plate adapted for different lengths ofnails.

` The nail-blanks are cut from the end ofthe plate with the taper inVaternate directions, heads and between each cutting. This is'aceomplisiiedby the 'semifiotation of the feeder.

are engaged by the ,cogs of the racks L, 'as the feedeis and the tableslide on the bed. Y

The racks are made to set out and in,so eitheiione maybe brought withinrange of the pinions 4onI the feeder, the other rack at. that timebeing` beyond the reach of the pinion'.

. The-racks L L ai'e set -out, by means of a sliding wedge, '-W,alongside o f th'ejbed.v

This is operated by lugs in, m onthe 'side' of the table, which engageprojections ou the wedge-slide and slip-it in one direction or other, toset ont the rack, which is not required during a certain. 'partof't-hcstroke of the table.

'One rack, L, comes into operation when the' table is moving in onedirection, and-the other rack when.. 'it is moving in the otherdirection.

ofthe nail-making machine, or each operation of the cutters', and, .whenit is moved the whole distance of 'the feeders and delivers a-blank fromeach plate, it becomes reversed by means of the double acting pawl '11,which is actuated by the contactof the stud 'c with .the arm J', a'spreviously stated.

The feeders are semi-rotated by the contact of their 'pinions with oneof the racks after delivering a blank, and the otheri'aek is made tofall back, to allow, the' pinions to pass.

'.llie table can be worked with one or more feeders, as desired. Y

' The end of the nai1`-plate,travels against the guard plate X, and isready to slip forward as soon as it reaches the gap where the cuttersare stationed.

The spring-plate 'l is' intended to hold ytheplate firmly, andalso toact as a gauge;v

Springs behind the racks L bear against them, to.

press them toward the sliding table when permitted by the wedge. I haveshown'the reciprocating table provided with -rotary feeders. lhe table,however, inay have nonrot-ating but r lat-ively stationary feeders; thatis, not tui-'ning the nailfplate between each cnt.

followers within the tubular feeders K by springs, or by cords andweights, or in :my other customary and A suitable manner.

' points. 'lo secure this result theplate is turnedover I 0n the e'nd ofthe barrel Kis a pinion, whose leavin;

The table is moved one section at cach revolution' '.lhe feed-movementmay be imparted to pushers oi I here not shown or described a-ny suchfeeding-np pliances, because they are common, and well under stood.-
